Why Is Only Half of My Nose Working?

The video explains the nasal cycle, a process where nostrils alternate in airflow to aid breathing and smell. This cycle is more noticeable during congestion. It helps maintain respiratory health by allowing cilia in the nasal passages to rest, preventing them from drying out. The cycle also enhances smell detection by varying airflow speed, allowing different odor molecules to bind to nasal receptors. The video concludes with a personal reflection on the nasal cycle.
